UNITED STATES PATENT EErCEo JOSIAII MASON, OF BIRMINGHAM, ENGLAND.

IMPROVEMENT IN PENS.

Specification forming part of Letters Patent No. 152,141, dated 51111615, 1874 applicati@ lefl April 30, 1874.

To all whom it may concern:

Be it known that I, JosIAH MASON, of Bir-V min gham, in the county ofIVarwick, England, have invented a new and useful Improvement in Pensand I do hereby declare the following to be a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being had to the accompanying drawingforming part ot' this specification, in which drawing- Figure lrepresents a front view of one of my pens. Figs. 2, 3, 4, and 5,respectively, are modifications ot' the same.

Similar letters indicate corresponding parts.

This invention relates to certain improvements in metallic pens; andconsists in the arrangement, upon the nibs of the pen and at a shortdistance from the point, of side cheeks or enlargements, for the purposeof arresting` the flow of ink on such sides and on the external surfacesot' the pen, the ink being supplied to the. point oi' the pen throughthe slits thereof, in such amanner that a uniform or nearly uniform owof ink is produced, and the danger of blotting by reason ot' anovercharged pen is averted.

In the drawing, the letter A designates a slip metallic pen constructedaccording to my invention. a ay are its nibs or tips, the outer sides ofwhich are expanded or enlarged, so as to form cheeks or scallops b b.These nibcheeks or enlargements are at a short distance from the pointofthe pen, and may have the semicircular form here represented, or anyother chosen form or shape. rIhe extreme points of the nibs a a-,thatis, the sidesA thereof beyond the cheeks b b-may either be parallel orslightly inclined to one another. Then the pen is dipped into ink theink is principally retained above the nibeheeks b b,

whereby the ilow or supply ot' ink to thev forms or modifications ofpens constructed acx cording to my invention. In these pens auxiliaryside cheeks b b are used in combination with the nib-cheeks b b justdescribed. These auxiliary cheeks b b form a part ot' the slip or shankA of the pen. In Fi g. 5 the nib-cheeks b b also form a part of saidslip or shank, instead of being on the side of the nibs, as in the otherfigures-that is, the shank ot' the pen is prolonged downward to near thepoint of the nibs, as represented in the drawing. In Figs. l and 2 thecentral slit of the pen passes beyond the nib-cheeks b b, opening intoan enlarged slit, e. In Fig. 3 a hole, d, is punched midway between thenib-cheeks b b, into which hole the aforesaid slit opens or vanishes. InFig. 4 the slit vanishes into the nib-cheeks b b, and each of thesecheeks is provided with a hole, d. In Fig. 5 the auxiliary cheeks b bare each provided with a hole, as shown, the end or nib cheeks remainingunpunched, while lthe central slit passes beyond the whole series ofcheeks.

.By the formation of side slits e e coincident with thel side outline ofthe nibs a a, said nibs of the pens, Figs. 2, 3, 4, and 5, are madeelastic, and may be made with or without the nibcheeks b b, as thegreater portion ot' the nibs is thus situated between and supported bythe auxiliary cheeks b b', the latter constituting reservoirs .t'orholding the ink, which is fed uniformly to the nibs in writing.

The pens move with great smoothness over the paper, and they are notliable to drop the ink or blot and spirtle the paper, as is coinmon toordinary steel pens.

These improvements are applicable also to barrel pens.

W'hat I claim. as new, and desire to secure by Letters Patent, is-

A metallic pen constructed with one or more pairs of cheek-nibs, b b',substantially as described, for the purpose described.
